Service manual for Teac A-X550?

[Xenon-Codex]

This seems to be hard to find. Does anybody have it or the schematic? A-X400 uses the same manual.

The replacement part arrived, but it does not work. Is there any way to get 7-pin RK14 50KC potentiometer for the bass-control? Everything else is available, but this reverse-audio taper(?) is not. The old has cracked taper which is not repairable.
Replacement part is acting weirly, if I turn bass to minimum, volume goes to max. It's supposed to be an 50K audio taper, but apparently without the C. It does affect correctlyu to the bass level in the max end.

I ordered two more pots, and again the first one was not working. It appeared to be broken(!). But the second works, after I cut the metal part so it would fit to the hole... 3mm needed to be cut.
